Marcos Alonso has signed a contract extension with Chelsea until 2023.

The Spanish international has established as a key player for the Blues since joining from Fiorentina in 2016.

After putting pen to paper on his new deal, the 27-year-old said: “I am so happy to stay here longer and to keep playing for one of the best teams in the world. It’s been a very good two seasons and I am looking forward to more.”

Alonso played at left wing-back under Antonio Conte and has successfully transitioned to left-back in a back four under Maurizio Sarri.

He has also proven to be a considerable asset going forward for Chelsea with 14 goals and seven assists in his 64 Premier League appearances for the club.

Club director Marina Granovskaia added: “We are delighted to be extending Marcos’ contract.

“In the past two seasons, he has developed into an important player for the club, demonstrating his outstanding ability and a fantastic attitude that has helped him become a Premier League champion and Spain international.”
